Comment (by vquicksilver):
Sorry the previous patch was intended for patching the kernel, but OpenWRT
uses the drivers in compat-wireless the following patch should work as
expected for debugging (I compiled trunk r41677 with it), just copy it to
./package/kernel/mac80211/patches/568-ath9k-debug.patch and build trunk
with it. (Yeah I'm a newbie with all this things sorry for that).
